JOSEPH J. LEIGHTON. OF BOSTON, MASSACHUSETTS.

Letters Patent No. 84,200, dated November 1-7, 1868.

IMPROVED 36x.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern Be it known that l, J'osnrn .T. Lmen'rox, of Boston, in-the county of Snflblk, and State of Massachusetts, have invented an Improved Wooden Box; and I do hereby declare that the following is a full and exact description thereof, reierenee being had'to the accompanying drawings, making part of this specification Figure 1 being a side view of the box.

Figure 2, a view showing the method of bending the material aroiuid a mandrel or form in making the box Like letters designate corresponding parts in both the figures.

The nature of my invention consists in a cylindrical or approximate formof box, composed of two or more layers of thin wood, wound spirally around the periphcry, each layer crossing the adjacent layer spirally, in opposite directions, so that their, grains shall cross each other, and the said layers being glued or otherwise secured together.

In the drawings, the outer layer A is shown wound spirally in one direction, and the inner layer B wound spirally in the'other direction, in relation to the axis of the box. Both the body of the box and the cover are formed in the same way. The bottoms and heads are inserted as usual.v

In making boxes by this method a cylindrical (or desired shape of) mandrel or form 0 (fig. 2) is prepared, having suitable slots 0 c, or other means. of clamping o'r scouring the ends of the strips of Wood thereto. Then the first or under strip B is attached or secured and wound around the form, so as to bring the adjacent edges thereof -in close contact, the strips having been. previously fomned of uniform width and with jointed edges for the pin-pose. The layer is then covered with a coat of glue, (when used,) and the next layer A, similarly prepared, is wound outside of the front layer spirally in the opposite direction, as shown in the same figm'e. Then, if another layer is to be added, it is wound around and secured to the layer A in the same manner as thatlayer is laid uponjhe layer 13. Thus any desired number of layers may be joined together, but generally two layers are sufiicient. The outer layer A may be aveneeiyof handsome wood, while the inner l yer B is of inferior wood.

The strips may be of any convenient length, so as 'to make more than one or even several boxes from .one tubular stock wound on the mandrel, by. cutting 05 transversely therefrom sections of the required lengths.

The box may be made very light, and still strong and durable. Its construction is quick and cheap.

' Vhat I claim as my invention, and desire to secure .by Letters Patent, is
